肌球蛋白重链 meaning in Chinese

mhc myosin heavy chain

Effects of exercise on myosin and convertion of muscle fiber types
运动训练对肌球蛋白重链及肌纤维转型的影响
Elevation of intracellular calcium ions may be partly induced by increased influx through sarcolemma l type - calcium channels . intracellular calcium elevation , on one hand , would activate calpain , a calcium - dependent cysteine protease that degrade the myofibrillar proteins and cause muscle atrophy ; on the other hand , result in activation of calcineurin which enhance the activity of mhc i promoter and inhibit a shift of mhc isoforms from slow to fast in soleus
这样，可能使得萎缩比目鱼肌细胞内钙离子水平升高，细胞内钙离子静息浓度的增加一方面激活calpain ，增加收缩蛋白的降解，使肌肉萎缩；草四军医大月卜祠成士学位论文另一方面通过激活钙调神经磷酸酶，增加快型mhc基因的表达，使骨骼肌肌球蛋白重链( mhc )发生由慢型向快型的转化。
